Abstract

A composite of manganese oxide (MnO₂) and Mn₃(PO₄)₂ decorated nanowires (MnO₂/Mn₃(PO₄)₂) was prepared using Lycium ruthenicum stem-extract mediated green synthesis. This composite material functions as an efficient and long-lasting electrocatalyst for water-splitting reactions, which could significantly improve the performance of oxygen evolution reaction (OER). The OER activity of MnO₂/Mn₃(PO₄)₂-based nanowires is boosted by blending with a conducting support, such as manganese oxide (MnO₂). The x-ray diffraction pattern and Fourier transform infrared data indicate that the nanowires are highly crystalline. The MnO₂/Mn₃(PO₄)₂ composite material demonstrates superior stability compared to its individual constituents and generates a current density of 10 mA cm⁻² at a low overpotential of 244 mV for OER in alkaline media. This research may lead to the development of MnO₂/Mn₃(PO₄)₂ composite materials as electrocatalysts for overall water-splitting reactions.
